Earlier quoted context omitted.

plus someone has no leverage whatsoever other than talking

Microsoft, famously resource-poor.

They have so much money it is harmful to their ability to execute.

Just look at the implosion of the XBox business.

Google has been using its own TPU silicon for machine learning since 2015. I think they do all deep learning for Gemini on ther own silicon. But they also invented AI as we know it when they introduced transformer architecture and they’ve been more invested in machine learning than most companies for a very long time.

I thought they use GPU for learning and TPU for inference, I’m open to been corrected.

The first tpu they made was inference only. Everything since has been used for training. I think that means they weren't using it for training in 2015 but rather 2017 based on Wikipedia.

It always falls back on the software. AMD is behind, not because the hardware is bad, but because their software historically has played second fiddle to their hardware. The CUDA moat is real.

So, unless they also solve that issue with their own hardware, then it will be like the TPU, which is limited to usage primarily at Google, or within very specific use cases.

There are only so many super talented software engineers to go around. If you're going to become an expert in something, you're going to pick what everyone else is using first.

So similar to Apple Silicon. If this means they'll be on par with Apple Silicon I'm okay with this, I'm surprised they didn't do this sooner for their Surface devices. Oh right, for their data centers. I could see this being useful there too, brings costs down lower.

> So similar to Apple Silicon. Yes, in the sense that this is at least partially inspired by Apple's vertical integration playbook, which has now been extended to their own data centers based on custom Apple Silicon¹ and a built-for-purpose, hardened edition of Darwin². ¹ https://security.apple.com/blog/private-cloud-compute/ ² https://en.wikipedia.org/wiki/Darwin_(operating_system)

Yeah, its interesting, years ago I never thought Apple nor Microsoft would do this, but also Google has done this on their cloud as well, so it makes sense.

The most important note is: > The software titan is rather late to the custom silicon party. While Amazon and Google have been building custom CPUs and AI accelerators for years, Microsoft only revealed its Maia AI accelerators in late 2023. They are too late for now, they realistically hardware takes a couple generations to become a serious contender and by the time Microsoft has a chance to learn from their hardwar…

At this point it will take a lot of investment to catch up. Google relies heavily on specialized interconnects to build massive tpu clusters. It's more than just designing a chip these days. Folks who work on interconnects are a lot more rare than engineers who can design chips.

Not suprising that the hyperscalers will make this decision for inference and maybe even a large chunk of training. I wonder if it will spur nvidia to work on an inference only accelerator.

> I wonder if it will spur nvidia to work on an inference only accelerator. Arguably that's a GPU? Other than (currently) exotic ways to run LLMs like photonics or giant SRAM tiles there isn't a device that's better at inference than GPUs and they have the benefit that they can be used for training as well. You need the same amount of memory and the same ability to do math as fast as possible whether its inference or…

> Arguably that's a GPU?

Yes, and to @quadrature's point, NVIDIA is creating GPUs explicitly focused on inference, like the Rubin CPX: https://www.tomshardware.com/pc-components/gpus/nvidias-new-...

"…the company announced its approach to solving that problem with its Rubin CPX— Content Phase aXcelerator — that will sit next to Rubin GPUs and Vera CPUs to accelerate specific workloads."

I don't know. The transformer architecture uses only a limited number of primitives. Once you have ported those to your new architecture, you're good to go.

Also, Google has been using TPUs for a long time now, and __they__ never hit a brick wall for a lack of CUDA.
